Definitions

  • Embodiments of the present disclosure relate to an in-ear headphone having a retention member for securing the in-ear headphone in the ear.
  • in-ear headphones also known in the industry as "earbuds”
  • earsbuds have gained popularity. This increase in popularity may be partly due to the generally smaller, lighter, and less obtrusive geometry offered by in-ear headphones compared to on-ear and over-ear headphones. Also, some people may prefer the sound generated by in-ear headphones compared to other types of headphones.
  • in-ear headphones offer advantages over other types of headphones, there are also some disadvantages associated with in-ear headphones. Among these disadvantages is the difficulty of designing in-ear headphones that are securely retained in the ears of most or all people.
  • the size and shape of each different person's ear is unique.
  • the size and shape of one of a person's ears may be different from the size and/or shape of that same person's other ear.
  • retention members for in-ear headphones have been developed for engaging with portions of the outer ear to hold the in-ear headphones in place in or over the ear canal.
  • many known retention members having a single size and design are not adequately retained in the ears of many users.
  • US 7,986,803 B1 discloses an ear bud earphone adapted for insertion in a user's ear.
  • the ear bud earphone comprises two or more tabs extending from the ear bud earphone, the tabs being substantially orthogonal to a longitudinal axis of the ear canal.
  • the tabs are adapted to engage the anti-helix of the ear.
  • US 2012/0039501 A1 discloses an earpiece including a positioning and retaining structure comprising at least an outer leg and an inner leg, each of the outer leg and the inner leg being attached at an attachment end thereof to the body and attached at a joined end to each other.
  • the outer leg lies in a plane. In its intended position, one of the two legs contacts the anti-helix at the rear of the concha, the joined end is under the anti-helix; a planar portion of the body contacts the concha; and a portion of the body is under the antitragus.
  • this disclosure includes retention members for an in-ear headphone that include a base portion configured for coupling to an audio driver housing and a substantially straight flexible finger extending from the base portion. Absent external forces, the flexible finger includes a substantially straight longitudinal axis, a back surface extending from a proximal end portion of the flexible finger proximate to the base portion to a distal end portion of the flexible finger distant from the base portion, and a plurality of recesses along a length of the back surface.
  • the flexible finger is configured to, during use, bend into a curved shape for disposition under a user's antihelix, such that portions of the back surface between the plurality of recesses abut against the user's antihelix and the distal end portion is positioned between the user's antihelix and crux of helix.
  • this disclosure includes in-ear headphones that include a shell, a nozzle extending from the shell, and a flexible retention member coupled to the shell.
  • the shell defines a volume housing an audio driver, and is shaped and sized to fit at least partially within a lower concha of a user's ear.
  • the nozzle defines a sound channel extending axially therethrough, the nozzle configured for insertion at least partially into the ear canal of the user.
  • the flexible retention member includes a base portion sized and configured for coupling to the shell, and a flexible finger extending from the base portion from a proximal end portion to a distal end portion.
  • the flexible finger includes, when not installed in the ear of a user and absent external forces, a substantially straight longitudinal axis, a back surface extending from the proximal end portion to the distal end portion, and a concave front surface opposite the back surface, the front surface extending from the proximal end portion to the distal end portion.
  • the term "substantially" in reference to a given parameter, property, or condition means and includes to a degree that one skilled in the art would understand that the given parameter, property, or condition is met with a small degree of variance, such as within acceptable manufacturing tolerances.
  • a parameter that is substantially met may be at least about 90% met, at least about 95% met, or even at least about 99% met.
  • any relational term such as “first,” “second,” etc., is used for clarity and convenience in understanding the disclosure and accompanying drawings and does not connote or depend on any specific preference, orientation, or order, except where the context clearly indicates otherwise.
  • any directional term refers to a direction from the perspective of a user of the in-ear headphone(s) described herein. Such directional terms are used to describe features of the in-ear headphone(s) when the in-ear headphone(s) is positioned in an initial orientation prior to and for insertion and use in an ear of the user. Unless indicated otherwise, the directional terms are also referred to herein absent any external forces that may deform (e.g., bend) any portion (e.g., a retention member) of the in-ear headphone(s).
  • the embodiments of the present disclosure include retention members for in-ear headphones and in-ear headphones including such retention members.
  • the retention members include a substantially straight flexible finger configured for positioning under an antihelix of a user's ear, to securely hold the in-ear headphone in the user's ear.

  • the back surface 130 may, in an initial, non-deformed position (i.e., absent external forces), be substantially straight from the proximal end portion 124 to the distal end portion 126.
  • the initial substantial straightness of the back surface 130 may enable the retention member 102 to be bent for use with a variety of different ear shapes and sizes, while maintaining pressure against the antihelix for a secure fit regardless of the particular ear shape and size.
  • the back surface 130 of the flexible finger 114 may extend from the base portion 104 substantially tangentially to the curve of the base portion 104.
